Hello! I've played this game for around 1.5 hours on my web browser, and wanted to share some of the things I noticed.
First of all, it looks absolutely amazing! The colors work together really well, and the mini tutorial was super helpful.
After playing for a while, I found that the number of items spawning in on top of the tiles was overwhelming, especially the ones used to create the color changing potion. I assume you will only ever need one of each potion, but I had to create a lot to keep getting rid of the ingredients.
I also loved the pumpkins, which I'm assuming are a seasonal thing, but I think they are spawning too fast because I have way more than I know what to do with. An option to discard tiles or items would also fix this problem.
^^(The attached screenshot should give you an idea of those ratios I mentioned above)
During my longer playthrough of the game, I never received any witch hats for some reason?
Pressing the menu button and using "new game" to return (it is my only option, but I think you already know about that bug) causes the first land tile envelope to spawn somewhere I've already placed a block. While it doesn't clear the world, it does clear the discovered material index. And I think causes my box to disappear, which is probably why I was overwhelmed by items.
I'm not sure what action I do causes this, but my trains will sometimes freeze in place perpendicular to the track they were previously following. This is easily fixed by picking up and re-placing the train.
After playing for a while, I stopped receiving any land envelopes other than the basic purple ones, so I wasn't receiving any dirt, stone or planks at all.
When my item envelopes would "disappear", I would go to the menu and re-enter using "new game", and they would be visible again. The envelopes do disappear again after that, so I have to repeat the process pretty often.
I'm sorry if it seems like I'm throwing a lot of criticism at you, that is not my intention. I really like this concept and where the game is headed, and I just wanted you to know what I though as a player.
A few quick details I really liked: you can change the color of the fence! Clicking the candles special item turns the flame on and off, and when lit they actually provide light!
again: great game, great artwork, and I'm looking forward to future updates!
